Product Description
Atomic Absorption Spectrophotometer ST-220
Higher Reliability* More than 40 years experience in AAS R&D and manufacturing
* Aberration eliminated C-T type monochromator with stable performance
* Modular electronic circuits design with easy operation and maintenance
* Reliable gas-liquid separator and fuel gas filter device provide the robustness even in high humid andharsh environment.
Higher Safety
* Intelligent feedback detection technique, real-time monitors the lamp current and protectsthe hollow cathode lamps.
* Simple structure modular gas supply system provides lower fault rate, higher safety and reliability.
* High precision mass flow controller and stable electronics in flame system control the fuel flow accurately. Temperature
control protection system together with dual air circuit breakers in GF system, effectively prevent current overload or abnormal temperature rise.
* Multiple safety interlock device and prompt information display prevent possible dangers.
More easy to use
* Unique light source system，with 8-lamp turret fully automatic change and optimization，supports1 lamp working and 7 lamps preheating in the same time.
* Easy changing emission burner for easily ionized elements such asK, Na, etc., with linear range 3 times that of normal flame.
* Temperature control modes in graphite furnace analysis can be switched over easily betweenoptical control and constant voltage control, according to different elements and graphite tubes, for the best results and extending the lifetime of graphite tubes.
* One-click automatic optimization, easy analytical condition setting, expert database support, for easy operation with no worries.
Fewer Faults
* Hamamatsu’s high performance PMT as the
* MoldingPPS spray chamber has high chemical stability, withstanding high temperature and strong acids .
* The communication system is based on the mature bussing technique. It improvesanti-jamming capability and data transmission reliability.
